Hey there! I'm currently working on a CLI tool to deploy WordPress apps to DigitalOcean. Check it out! It's free and open source.
I wrote before that I’ve been running some experiments with Varnish lately. Not that I have huge traffic here but I’ve always used my own website to test things out. As I wrote earlier, the problem with WordPress and Varnish is that WordPress relies on cookies which create cache misses on Varnish and in that previous post I shared a snippet on how to strip all incoming and outgoing cookies, which hopefully solves one problem.
Note that the plugin can fail if you’re rendering your comment form differently (with different DOM IDs) from WordPress, and don’t forget to purge.url your Varnish cache after activating!
